Concrete and preparation method thereof.
Background technology
With the rapid development of the national economy, engineering structure Chao Genggao, bigger, stronger direction develop, this is to concrete
Performance proposes new requirement.With the progress of science and technology, ultra-high performance concrete is the Main way for solving this problem
One of.Ultra-high performance concrete has good durability, can increase substantially the service life of concrete structure.Meanwhile
With excellent mechanical property, it can significantly reduce scantling.In general, ultra-high performance concrete dead load is approximately to pass
The 1/3 or 1/2 of system concrete structure, can effectively subtract dead load, save material and cost.But current engineer applied is not
It is more：Some are because cost is too high, and some are because technology of preparing is too complicated, and some then the liquidity scales while intensity improves
Decline and can not be applied among engineering.Therefore, to meet to be currently needed for, the very-high performance life of large fluidity low cost is configured
State concrete, just seem extremely necessary.
At present for ultra-high performance concrete, although existing a small amount of engineer applied, most of to remain in reality
Room conceptual phase is tested, existing ultra-high performance concrete often uses high temperature or steam press maintenance, complex manufacturing limit in production

1000kg/m3, the heat of hydration is increased, produces contraction.Therefore, it is necessary to invent a kind of novel ecological concrete, cement consumption is reduced,
Reduce and prepare cost, improve concrete flowability, and simplify production technology.
It is every in building material itself to pass through a series of physical, chemical action, or mixed with other materials (such as water)
Hard solid can be become by slurry by a series of physical, chemical action together afterwards, and can be by loose material (such as sand, stone
Deng) or block, flaky material (such as brick, stone) cementing integral material, referred to as binder materials.
Cement is the binder materials being commonly used, still, on the one hand, manufacture of cement power consumption is very big, accounts for world's total energy
Consumption 15%, China's cement produces more than 200,000,000 tons per year, ranks first in the world, but China's cement specific energy consumption reaches 5280KJ/kg, compares generation
Boundary cement average unit energy consumption 3260KJ/kg is high by 60%, and production energy consumption issues are especially prominent.All kinds of mineral moneys in another aspect China
Source is very abundant, and industrial residue largely overstocks, and takes tract pollution environment, anxious utilization to be developed.Develop the low glue of energy consumption
Gel material, while and can consumes substantial amounts of mineral resources, industrial residue needs to solve the problems, such as us.
